TOOL-HOLDER.

SPECIFICATION forming part of Letters Patent No. 274,232, dated March 20, 1883.

- Application filed November 8, 1882. (No model.) i

pertains to make and use the same, reference being had to the accompanying drawings, and to letters or figures of reference marked thereon, which form a part of this specification.

Our invention relates toan improved device for holding hand instruments or tools-such as pinchers, due-whereby said tools may be operatedby means of a treadle or other suitable power-connection.

Our invention consists ofa portable frame or holder, made of metal or other material, in

connection with a suitable clamping device which permits of theinstrument being readily attached to the holder, or detached therefrom when desired.

it is found in practice that a portable detachable holder for setting -instrun1ents pinchers or other analogous tools-which can be readily attached to atable or bench in stores or workshops is very desirable. The object of our invention is to produce such a holder which will retain such tools, and in a com paratively inexpensive manner.

In the drawings, Figure 1 represents a vertical front elevation of our invention, having a setting-instrument attached, and showing a portion of the clamping device in section.

. Fig. 2 represents a side elevation of the same,

with instrument, &c., removed. Fig. 3 represents details of the clamping device.

A represents the frame or holder, which is preferably made of iron, having arms or projections a a at its upper end. Said arms are of a V form on top, and are designed to receive and retain the arm or handle of any hand-instrument when placed therein, in connection with the upper clamping-piece, B, the under side of which has also a V-shaped groove thereper end of said bolt terminating in an eye or ring provided with a cup-shaped recess, d, at the upperinner side of said ring.

The holder or frame A is secured to the table or bench by means of screws passing through the legs or feet of said frame. The frame is further provided with a central hole through which the clamping-bolt U loosely passes.

E represents an extension-piece, which is attached to the free arm or handle of the instrument. Said piece has connected thereto the rod or connection g, which latterin turn is attached to a suitable treadle or other device at its lower end, whereby the same may be operated by foot-power, 8w. Aspring, H, serves to open the instrument when the pressure upon bench, one handle of the tool is placed in the V-groove of the holderat a a, and through the eye of the clamping-bolt (J, after which the upper clamp, B, is alsoinserted, the V-groove thereof resting upon theupper side of the toolhandle when the projection b of the clamp B is brought in contact with the corresponding recess in the eyebolt, and the whole clamped firmly together by means of the nut D, the projection b and its recess forming a self-adjusting clamping device for the tools. By attaching the extension-pieceE to the end of the free handle the instrument is then made ready for use. piece E and attach the connection 9 direct to the handle.
